Abstract (en)
[origin: US2016268555A1] A light emitting element includes: a concave-convex structure layer, a first electrode, an organic layer, and a second electrode layer provided on a surface of a base member in this order; and a lens member arranged on an opposite surface of the base member on a side opposite to the surface, wherein a center of the lens member is coincident to a center of a light emitting portion in a plane view, the light emitting portion being an area of the organic layer between the first and second electrodes in a base member thickness direction; ratio of diameter D2 of the light emitting portion to diameter D1 of the lens member satisfies D2/D1≦0.7; and ratio of distance d to diameter D1 of the lens member satisfies d/D1≦0.25, distance d being between the opposite surface of the base member and the center of the light emitting portion.
